IPv8 Routing
IPv8 routing is described across the core IPv8 draft and companion routing specifications. The core draft introduces the main expectations and references related documents for more detail.
Routing Protocols
Section titled “Routing Protocols”| Protocol | Draft role |
|---|---|
| BGP8 | Mandatory exterior gateway protocol. |
| IBGP8 | Inter-zone routing. |
| OSPF8 | Intra-zone routing. |
| IS-IS8 | Optional interior gateway protocol. |
| CF | Cost Factor, a unified path quality metric. |
Cost Factor
Section titled “Cost Factor”The draft describes Cost Factor as a 32-bit accumulated metric derived from telemetry such as round trip time, packet loss, congestion state, session stability, link capacity, economic policy, and geography.
The geography component is described as a physics floor. A route that appears faster than the speed of light over the relevant distance can be flagged as a Cost Factor anomaly.
Global Table Bound
Section titled “Global Table Bound”The draft presents BGP8 routing as bounded by ASN count instead of unconstrained prefix count. It also describes a minimum injectable prefix rule intended to reduce deaggregation.
Route Validation
Section titled “Route Validation”BGP8 route advertisements are validated against WHOIS8 before installation in the routing table. The draft frames this as a way to reduce prefix hijacking risk and remove manual bogon list maintenance.
Companion Draft
Section titled “Companion Draft”More detail is expected in draft-thain-routing-protocols-00, listed on Companion Specifications.
